ORLANDO, Fla. — Asian American households saw the biggest income growth of any racial or ethnic group in the United States over the past decade and a half — almost 8%, according to figures released Thursday by the U.S. Census Bureau.

Household income for Latinos grew by nearly 6% over that time, while households led by non-Hispanic whites and Blacks had comparatively stagnant income growth — 3% and almost 2%, respectively — over the past decade and a half.

Nationwide, median household income grew 2.3% from the 2005-09 period to the 2015-19 period, according to the latest fiveyear American Community Survey.

Economists said a lot of the difference in income growth among racial and ethnic groups has to do with the thriving job markets where Asian American and Latino-led households are concentrated — cities and communities in the West and Southwest.

“As the labor market tightened more in certain areas and in certain fields, we would see more robust income growth for those groups,” Ohio State economist Trevon Logan said in an email. While income growth has been comparatively flat in a vast majority of U.S. counties, it has been concentrated in a handful of communities, said William Spriggs, an economist at Howard University.

“So, I suspect recent Asian and Latino immigration has been to these high growth areas,” Spriggs said.

Education also played an important role, said Marlene Kim, an economist at the University of Massachusetts at Boston.

More than 54% of Asian Americans had a bacheAbove, commuters in New York City. DONALD KING/AP2018 lor’s degree, the highest of any racial or ethnic group, compared with 32% overall for U.S. residents, according to the 2015-19 American Community Survey.

By comparison, 35.8% of non-Hispanic whites, 21.6% of Blacks and 16.4% of Latinos had bachelor’s degrees.

“We are in a knowledge economy, and a college education is key to getting professional jobs that pay well. Asians have the highest percentage of getting a college degree, and I think you are seeing that effect,”

Kim said. “Asians are more likely to be in professional and technical jobs, which are thriving and increasing their pay and income level.”

By the same measure, location and job markets also played a role in the stagnant income growth for Black-led households, with large numbers geographically clustered in the South, economists said.

“For Black households, we continue to see them struggle for the same reasons. Blacks are overrepresented in public employment, which experienced anemic income growth,”

Logan said. “Also, Blacks in rural areas, especially in the rural South, are located in places with substantial business losses and weak job growth.”

Discrimination in hiring and promotions also are factors as well as policy decisions, he said.

“For example, we know increasing the minimum wage would close racial income gaps, and Blacks are disproportionately located in states, localities that have not done so,” Logan said.

The concentration of Black high tech workers in places like Atlanta and Washington instead of Silicon Valley or Boston also worked against income gains for Black households, Spriggs said.

Households led by Asian Americans had a median household income of $88,204 over the five-year period covered by the 2015- 19 American Community Survey, the highest of any racial or ethnic group. Asian Americans make up almost 6% of the U.S. population.

Nationwide, the median household income for 2015- 19 was $62,843.
